Title: Pll receiver
Inventor: NORITA KAZUYUKI
IPC: H03J5/02
Filed: 1987-07-28
Abstract: PURPOSE:To attain accurate reception by giving a varied numeral N to a local oscillator and correcting it based on a phase difference to reduce the time required till the PLL system is settled thereby h improving operability such as search. CONSTITUTION:A digital signal processor DSP 14 outputs a reference digital value to a D/A converter 15 in response to a numeral outputted from a microcomputer 9 and the analog output is fed to a local oscillator 3, and its local oscillation output is fed to the mixer 4 and a programmable divider 11. The signal subjected to 1/n frequency division by the divider 11 is given to a phase comparator 12, where the phase difference from a reference signal is detected and a phase difference output is subjected to digital conversion 13 and the result is fed to a DSP 14. Thus, the DSP 14 corrects the reference digital value to feed back it to the oscillator 3 via the D/A converter 15.

Title: Storage medium
Inventor: KUBOTA MICHITAKA
IPC: G09G5/00
Filed: 1997-07-14
Abstract: PROBLEM TO BE SOLVED: To provide a storage medium of a new form which assures a profit even when a purchase unit cost is lowered by enhancing a value added with a higher functionality. SOLUTION: A digital electronic still camera 6 using this semiconductor memory 1 is constituted of a slot 7 into which a semiconductor memory 1 is inserted and a liquid crystal monitor 8. Value information, for example, advertizing information and picture is previously stored into the semiconductor memory 1 and each time a user inserts the semiconductor memory 1 into a digital electronic still camera 6, specified time is displayed on the liquid crystal monitor 8 during a period until an output of the value information is limited. This can lower the cost of the storage medium by a value equivalent to an advertising cost when the value information is the advertising information while allowing differentiation from similar products.

Filed: 1983-10-11
Abstract: PURPOSE:To enable high-speed scanning and to improve resolution by performing scanning while converting the spot image on a line to the spot image on a circumference by using optical fibers thereby eliminating linear forward and backward moving parts. CONSTITUTION:Optical fibers 11 of which the inlet parts 11a are linearly arranged flush with the side surface part 10a of a base plate 10 and the outlet parts 11b are arranged in an arc shape flush with the arc-shaped side face part 10b of the base plate, respectively at an equal pitch, are arranged on the base plate 10 and a rotary mirror 20 is disposed in the central position of the circle of said arc. The light alpha emitted from, for example, a spot image (a) on a document A enters the inlet 11a proximate thereto, passes through the fiber 11 and is radiated from the outlet 11b. Said light is reflected by the mirror 20, is stopped down by a lens 40 and enters an opto-electric transducer 30, by which the light is converted to an electric signal. Then the high-speed scanning is made possible as there are no linear forward and backward moving parts. Both durability and resolution are thus improved.

Title: Microcomputer
Inventor: MATSUI SATOSHI
IPC: G06F7/508
Filed: 1988-07-28
Abstract: PURPOSE:To reduce the total shift and addition frequencies necessary for the multiplication of a single time to perform the multiplication at a high speed by dividing the multiplication every two bits to perform the shift and addition operations every two bits. CONSTITUTION:A multiplier (A) is divided every two bits and set at an accumulator 4, and a multiplicand (B) is set at an input latch 5b of an arithmetic logic unit ALU 5. At the same time, a partial product (C) is set at a latch 5a. A control signal output circuit 9 decides a mode (M1) where the C is outputted as it is, a mode (M2) where the B is added to the C, a mode (M3) where the double B is added to the C, or a mode (M4) where the B is subtracted from the C according to the values of the lower rank bits of the B. Then the circuit 9 produces a signal S. The ALU 5 carries out a process based on the signal S and sets the result of this process at the latch 5a or 5c. Such operations are repeated by n/2-bit times to complete a multiplication process (AXB) except a correction process. As a result, the total frequency of additions can be decreased and the multiplication is carried out at a high speed.

When decrease of water supply is requested, the r.p.m. is decreased and the outlet valve is closed in the direction contributive to decrease water supply with no time lag. The outlet valve is fully closed at the r.p.m. Na corresponds to the lowest r.p.m. and low flow rate water supply flow control is conducted stably in the region above the lowest r.p.m.

Filed: 1990-07-19
Abstract: PURPOSE:To compensate wearing even if the surface of a carrier is worn by a recording sheet, and to maintain contact pressure required for a blade and an excellent cleaning effect by increasing the contact pressure of the blade coming into contact with the surface of an image carrier. CONSTITUTION:The blade 4 comes into contact with a photosensitive body layer 2 with the contact pressure so as to surely scratch off toner sticking to the body layer 2 of a photosensitive drum 1 on a part except the central part of the edge part of the lower side, and the central part comes into contact with the photosensitive body 2 with the contact pressure higher than that of both end parts. Then, the drum 1 is rotated, so that the edge 4a of the blade 4 scratches off the toner stuck to the body layer 2. Thus, even if the body layer 2 is shaved by sliding with the recording sheet and worn and the diameter of the part coming into contact with the recording sheet is gradually made small, the entire blade 4 in a longitudinal direction comes into contact with the entire body layer 2 in a transverse direction with prescribed contact pressure, to scratch off the toner stuck to the body layer 2. Therefore, this cleaning device can always clean the drum 1.

Title: Preparation of highly heat resistant catalyst for purifying nitrogen oxide
Inventor: TANABE TOSHITAKA
IPC: B01J29/068
Filed: 1994-07-19
Abstract: PURPOSE:To control the thermal deterioration due to exhaust gas containing water by further ion-exchanging an alkali metal cation obtained by ion- exchanging ammonium ion in ammonium type zeolite, with a catalyst metal so that the catalyst metal is supported on the zeolite. CONSTITUTION:When ammonium ion in ammonium type zeolite is ion-exchanged with an alkali metal cation, the ammonium ion which causes the generation of Brphinsted acid points is replaced with the alkali metal ion. Since the alkali metal ion is monovalent, most ammonium ion is replaced by the alkali metal cation. Next, the alkali metal cation is further ion-exchanged with the catalyst metal so that the catalyst metal is supported on zeolite. Since the residual alkali metal ion is not hydrolyzed in the following burning process, the generation of the Brphinsted acid points can be controlled.
